A Survey of Refractory Industry in Eastern India
No full textThe Refractory Industry in Eastern India is concentrated round the coal field area which incidentally houses the major part of India’s Heavy Metal Industry. Thus the Industry is ideally located both as regards the raw materials that it needs, as well as the markets that its products demand. Whereas The Refractory Industry is running under a great strain with a large demand that it finds difficult to cope with. Thus delivery periods of eight to ten months even on small orders are the rule rather than the exception. It is felt that the two suggestions if taken up will be very welcome to the industry and will help her to give better and more economical service. Consumers will also benefits in the ways enumerated in this survey
Separations of Magnesite, Dolomite and Siliceous Minerals from Limestone, by Ore-Dressing Methods
No full textIt is reported that Patiala State in East Punjab has very extensive deposits of Limestone, running to many million tons, but its magnesia content is too high to be used as it is, for cement manufacture. To enable these deposits to be exploited for utilisation by the cement industry, the magnesia content has to be brought within the prescribed limits by any of the known processes. An attempt is made in this report to present all the methods available from current literature, for the separation of limestone from magnesite, dolomite and siliceous minerals, by ore-dressing methods
Possibilities of Manufacture of Alumina by Serpek Process
No full textAluminum is an element that was discovered in 1825 and its commercial history of it covers only 60 yrs, It is one of the principal metallic products of the electrochemical industry. The principal ore of aluminum, bauxite comprises the hydrated oxides of aluminum, Al203, H20 which is known as diaspore, and Al203,3H,02 which is known as gibsite, together with associated impurities such as the oxides of iron, silicon, and titanium. Bauxite is produced by the weathering and alteration of aluminium silicate rocks and is widely distributed around the world usually in tropical. and semi-tropical regions, where the weathering process have proceeded at an accelerated pace, The bauxite deposits in India are primarily in Bihar, Central Provinces, Central India, Bombay Presidency, Madras, and Kashmir. These deposits consist of gibsite and diaspore as well as a mixture of both in different proportions. Indian bauxites are of superior quality with low silica content (0,9 25%) and rich in titania (8-13%), Total production of bauxite during 1938 was 14, 768 tons
National Metallurgical Laboratory of India
No full textThat India possesses great natural advantages for the production of iron and steel there is no doubt. She has rich and vast deposits of iron ore, exceeding both in quality and quantity the ores found in many States of Europe and America
Studies on Indian refractory clays –examination of some clays by differential thermal analyses. x-ray and electron microscopic techniques.
No full textThe mineralogical constitution of ten domestic refractory clays and the morphs logical characteristics of the principal clay mineral present in them have been studied by differential thermal analysis, x-ray powder diffraction, and electron nicr0- scopes techniques
